Fogged Exterior Light Lenses
The inside lenses of exterior lights (headlights, brake lights, etc.) may fog temporarily
if you have driven in the rain. Dew condensation also may build up inside the lenses
when there is a significant enough difference between the ambient and inside lens
temperatures (similar to vehicle windows fogging up in rainy conditions). These
conditions are natural processes, not structural design problems in the exterior
lights.
Lens design characteristics may result in moisture developing on the light lens frame
surfaces. This also is not a malfunction.
However, if you see large amounts of water accumulation, or large water drops
building up inside the lenses, have your vehicle inspected by an authorized Acura
NSX dealer.

Carbon Ceramic Brakes
Keep the brake pads and rotors free of substances that are either abrasive or oil
based, as these substances can reduce braking power.
When driving in the presence of salt and/or sand, briefly wash the rotor/pad surfaces
with low-pressure water, and then brake the system dry to help maintain the brake
system's performance.
Brake maintenance requires specialized knowledge. We recommend maintenance
to be carried out by an authorized Acura NSX dealer.
